> Domestic or hobbyist 3d printing is not going to produce a particularly strong gun, it's most likely going to only work once or twice before it blows itself apart. There is a good chance the person using it will significantly hurt themselves. While this is true for 100% printed guns, most fosscad folks will have core components that are metal. Barrels, firing pins, etc will be metal in most designs. Some folks claim their guns can shoot thousands of rounds with no issue. > They will have very poor accuracy, it won't be possible to rifle the barrel on a 3d printed gun in a way that will spin the projectile. Folks literally etch their gun barrels with the same specs as commercially available barrels. Here is one such example from the /r/fosscad community: https://www.reddit.com/gallery/106u7au https://www.reddit.com/gallery/106u7au While the fear is mostly media driven, the stuff folks are making now is a little alarming. Claymores, grenade launchers, etc. If you are interested in learning about this community, check out /r/fosscad on reddit.

> Some folks claim their guns can shoot thousands of rounds with no issue. For context, I have an AR with a printed lower that I've put ~1k rounds through without issue. In the US that's the only serialized part, and therefore the only part that would be typically purchased from a dealer and able to be "traced". > Folks literally etch their gun barrels with the same specs as commercially available barrels. I've made a couple of pistol barrels with ECM, and they're no less accurate than commercial stuff. It might be interesting to know that I made those specifically in order to comply with US law - not to "evade" it. Even a single-shot rimfire pistol falls under the National Firearms Act unless it has a rifled barrel. It would have been much simpler to just use a metal tube, but I didn't want to deal with filing the forms, paying the tax, and waiting months for approval before putting together a random project that I started on a whim.
